So, yes, we face a threat to our capitalist system. But it's not coming from half-naked anarchists manning the barricades at Occupy Wall Street protests. Rather, it comes from pinstriped apologists for a financial system that glides along without enough of the discipline of failure and that produces soaring inequality, socialist bank bailouts and unaccountable executives.

Just a few months ago, I wrote a piece for Adbusters that started with a conversation I'd had with an Egyptian activist friend named Dina:

All these years," she said, "we've been organizing marches, rallies… And if only 45 people show up, you're depressed, if you get 300, you're happy. Then one day, 200,000 people show up. And you're incredulous: on some level, even though you didn't realize it, you'd given up thinking that you could actually win.

As the Occupy Wall Street movement spreads across America, and even the world, I am suddenly beginning to understand a little of how she felt.

Karl Marx was right, it seems, in arguing that globalization, financial intermediation run amok, and redistribution of income and wealth from labor to capital could lead capitalism to self-destruct. So what can be done to prevent that outcome?

But the problem is that we live in a society where capitalism itself has become rampantly feral. Feral politicians cheat on their expenses, feral bankers plunder the public purse for all its worth, CEOs, hedge fund operators and private equity geniuses loot the world of wealth, telephone and credit card companies load mysterious charges on everyone's bills, shopkeepers price gouge, and, at the drop of a hat swindlers and scam artists get to practice three-card monte right up into the highest echelons of the corporate and political world.

The media has been so preoccupied with acute symptoms of the debt crisis - sliding home prices, foreclosure abuses, ongoing Euromarket bank/sovereign debt stress, ongoing battles over financial regulation implementation, unhappiness over the Fed's QE2 - that lingering problems are not getting the attention they deserve.

High on the list is the how the weak job market is affecting new college and advanced degree program graduates. We have an unspoken social contract: young people who get an education, particularly a "good" education (which means more elite universities, more serious courses of study, graduate degrees) are supposed to be rewarded by higher lifetime earnings. And the prospect of higher lifetime earnings in turn makes it rational to borrow to invest in education.

But this whole premise has started to go awry, and the huge uptick in unemployment has started to make matters worse.
